From 67843bbaf36eb087714f40e783ee78e99e9e4b86 Mon Sep 17 00:00:00 2001 From: Suzuki K Poulose Date: Tue, 23 Jul 2019 23:18:34 +0100 Subject: drivers: Introduce device lookup variants by fwnode Add a helper to match the firmware node handle of a device and provide wrappers for {bus/class/driver}_find_device() APIs to avoid proliferation of duplicate custom match functions.
